Are you OK that consciousness is, from the first person perspective, something which can be said to be 1) true 2) knowable 2) non provable 3) indubitable 4) non definable 5) anticipable If yes, then all universal machine is confronted with this, although only Löbian machine can assert this, with precaution. Consciousness is not much more than the first person belief in some reality. It accelerates the learning of distinguishing prey and predators for the self-moving self-eating types of creatures. There are many possible experience of consciousness, and even sorts of state of consciousness, from highly dissociative, with or without amnesia, to many mundane state, like each of us at all instant of our normal waking life. It makes easy to get new beliefs and to abandon ancient beliefs. When Löbian, it generates “fear” (the local expectation of local unsatisfiabilty condition).
